1997 buick life
I have seen many with 400,000 miles and still going. Long life average is impossible to average or tell as the engine life beyond the first 100,000 is 100% based on driver habits and how the maintenance is done.
About 30,000 to 45,000 miles for an average mileage life of a vehicle engine for each of the major manufacturers. Some numbers may differ if you are harsh to your cars, you gun the motor, squal out and such is bad. Your car is to get you from point A to point B and any other place you wish to go.
No, you can and should use high mileage oil if the vehicle has over 100,000 on the ODO.
depends on how you treat it.
It has a timing chain that should last the life of the engine.
The timing chain has no set date or mileage for replacment. It will normally last the life of the engine.
I just got one with over 270,000 miles
My 1995 Buick Regal Transmission just went out at 249,000, but everything else still works.
a knock sensor will retard or advance ignition spark, improving gas mileage and will not shorten engine life , if any thing it will extend engine life.
The timing chain is designed to last the life of the engine.
The total mileage a car can last is completely up to the driver. With routine maintenance, oil changes, and check-ups, you will get much more life out of your vehicle. If it is not cared for, it will not run as long.
